re: How much will GameStop give me for a PS3?(Posted by B1rdman15 on 1/12/13 at 7:42 pm to RudeDog11)

1 Look at the number of USB ports on the front of the console. If your PS3 has four USB ports, it's probably a model with backward compatibility for PS2 games. If it has two, it is not.

2 Check the back of the console for more precise information about your model. There will be a label that includes your PS3's model number. The model number begins with the letters CECH. You have backward compatibility for PS2 games if the model number begins CECHA, CECHB, CECHC, or CECHE. All other models are incapable of running PS2 software.
